在Oracle10g RAC的安装过程中，网络的设置需要谨慎，也极其重要。

以下将我的Oracle10g RAC环境的网络配置列举一下，供参考。

1.hosts文件的设置

由于RAC要设置多个地址，所以需要准备好网络环境，我的hosts文件设置如下：

# # Internet host table # 127.0.0.1 localhost 172.16.19.11 db210-rac1 db210-rac1.hurray.com.cn loghost 172.16.19.211 db210-rac1vip db210-rac1vip.hurray.com.cn 192.168.18.11 db210-rac1priv db210-rac1priv.hurray.com.cn 192.168.19.11 db210-rac1hb db210-rac1hb.hurray.com.cn 172.16.19.12 db210-rac2 db210-rac2.hurray.com.cn 172.16.19.212 db210-rac2vip db210-rac2vip.hurray.com.cn 192.168.18.12 db210-rac2priv db210-rac2priv.hurray.com.cn 192.168.19.12 db210-rac2hb db210-rac2hb.hurray.com.cn

2.监听器的配置

我的监听器文件配置如下：

bash-2.05$ cat listener.ora # listener.ora.db210-rac1 Network Configuration File: /opt/oracle/product/10.2.0/db/network/admin/listener.ora.db210-rac1 # Generated by Oracle configuration tools. LISTENER_DB210-RAC1 = (DESCRIPTION_LIST = (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = db210-rac1vip)(PORT = 1521)(IP = FIRST)) ) (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = 172.16.19.11)(PORT = 1521)(IP = FIRST)) ) (ADDRESS_LIST = (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC)) ) ) )

3.tnsnames.ora文件配置

网络服务名等配置如下：

bash-2.05$ cat tnsnames.ora # tnsnames.ora Network Configuration File: /opt/oracle/product/10.2.0/db/network/admin/tnsnames.ora # Generated by Oracle configuration tools. EYGLE2 = (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = db210-rac2vip)(PORT = 1521)) (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = eygle) (INSTANCE_NAME = eygle2) ) ) EYGLE1 = (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = db210-rac1vip)(PORT = 1521)) (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = eygle) (INSTANCE_NAME = eygle1) ) ) EYGLE = (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = db210-rac1vip)(PORT = 1521)) (ADDRESS = (PROTOCOL = TCP)(HOST = db210-rac2vip)(PORT = 1521)) (LOAD_BALANCE = yes) (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = eygle) (FAILOVER_MODE = (TYPE = SELECT) (METHOD = BASIC) (RETRIES = 180) (DELAY = 5) ) ) ) LISTENERS_EYGLE = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = db210-rac1vip)(PORT = 1521)) (ADDRESS = (PROTOCOL = TCP)(HOST = db210-rac2vip)(PORT = 1521)) )

这就是主要的一些配置文件，其中，Oracle的相关配置文件都是自动生成的，VIP可以实现故障时的自动切换。
